Depends on how big you budget is i persnoly have a JDM 98+ Spec ITR in my HB and its pretty fast. Cost me $6150 Total Installed, parts needed, + engine. B16 are a waste in my opinion i ran a turbo B16 from a dig and beat it by 1/2 a car it was laying 300whp then ran a B16 w/ cams, cam gears, headers, intake, and exhaust beat it by 3/4 cars. I would go w/ an ls over a B16 lots more potential
